In recent years, web 2.0 technologies (such as wikis, blogs, and social networking sites) have been added to the effectiveness of the internet as an enabler for developing, storing and disseminating information to large audiences of people in diverse locations, instantly, and at fairly low cost.
And, as a three months web information analysis has recently found, there are a significant – and rising – number of users of web 2.0 technologies in Africa.
Wikis are conversational technologies with broad knowledge management capabilities that employ an unconventional knowledge creating and sharing paradigm where there is no cast-in-stone circle of authors. Rather, the knowledge creation process is incremental.
Whereas wikis have been hailed for revolutionising the information age (for instance, Wikipedia has within a few years become the world’s largest Open Content project achieving millions of articles and outnumbering all other encyclopedias), they have also been faced with criticism of the validity of their information.
Amongst internet users, Wikipedia is the 8^th top site in the world. In Africa, it is most popular in South Africa and Madagascar, ranking 6^th and 7^th respectively.
Being edited by everyone capable of doing so, the validity of wikis depends on the knowledge of who does the editing, as well as on the more frequently visited subject matters that are continuously improved and commented upon. Moreover, some wiki pages that are not visited at all lack combined knowledge contributions and thus may not be accurate or may be speculative.
The social networking site Facebook to date has 500 million active users. Half of them log in daily and the average user has 130 friends in use. It is ranked the 2^nd most visited site in the world. Amongst African countries, it is either the number 1 [9 countries] or number 2 [5 countries] most used website.
Users of social networking sites form a network that provides a powerful means of sharing, organising, and finding content and contacts.
Blogs (online diaries maintained by an individual with regular entries of commentary, descriptions of events or material, graphics and video) are popular too. They combine text, images, links and other media and also allows interactivity by way of comments. According to Alexa.com traffic figures, Blogger is the fifth most popular website in the world. On the African continent, it is the 5^th most popular in Nigeria, 6^th in Kenya and 8^th in Uganda, Mauritius and South Africa.
Twitter, a social networking and micro blogging service that utilises instant messaging, or a web interface is the 9^th most popular website globally. South Africans, Nigerians, Kenyans and Ugandans are at par with the rest of the world; ranking 7^th – 8^th of their internet traffic.

Clearly, web 2.0 technologies allow for more efficient and speedier generation, exchange, sharing and modification of multimedia content.
The key features of the interactive, online media, that often make them popular with users include their interactivity (users may communicate on a many-to-many reciprocal basis); and they are a global network as communication is not fettered by nation-state boundaries. Besides, there’s free speech as internet users may express their opinions with limited state censorship; and they enable free association since net users may join virtual communities of common interest. But do these advantages explain why social media has caught a fire in Africa?
